Sample Analysis: 3-Ton System
Demo Analysis — See what your results could look like
Your current system is oversized. Consider downsizing by 15-30%.
Right-Size System
2.5-Ton(30,000 BTU/hr)
Your Current System
36,000 BTU/hr (3.0 tons)
Your Home's Actual Need
22,680 BTU/hr (1.9 tons)
Measured from your thermostat data
What to do next
When replacing your system, ask your HVAC contractor about downsizing. A smaller system runs longer cycles, dehumidifies better, and costs less upfront.
